Not really entertaining.
Animation/Graphics - The animation and graphics were the best part about the flash. The drawings kind of had to be good since they were sprites and everything, but you did a really good job on animating them smoothly. So very smooth animation and this is basically where you got most of your points in my review from.
Story/Content - Kind of boring to be honest. I don't think that sprites are the right choice for a dance song. Maybe that's just my opinion, but it just wasn't very entertaining at all. I do like the interactivity that you had in the flash by adding the buttons and even having the character saying your name though. Perhaps you could have made it a little bit better by adding more dancing/dancers, etc.. Also, the way he died at the end was kind of random and completely weird.
Audio - I think you could have chose much better music for the flash. Perhaps that's my opinion on disliking the genre, but hell.
Overall - Not really entertaining to watch or anything.
